Waterphones are stainless steel and
bronze monolithic, one-of-a-kind, acoustic, tonal-friction instruments
that utilize water in the interior of their resonators to bend tones
and create water echos.
The rods can be played with superball
mallets, by hand or with a bow. When the tonal rods are sounded
some of the fundamental tones and/or harmonics are sympathetic to
the bottom & top diaphragms.
When the attitude of the Waterphone
is changed from vertical to horizontal and all in between the water
is being moved on and off the bottom diaphragm as the tones are
The water acts in 2 ways - (1) to bend tones via
the weight of the water on the bottom diaphragm which lowers the
tone when the Waterphone is in the vertical position and raises
the tone when in the horizontal position and (2) creates acoustic,
schiziosonic, modulations as in pre-echoes via the motion of the
water and the relative speed of sound in water, air and metals.
